Abstract

Un método comprende proporcionar una resina que comprende un copolímero en bloque de olefina; hilar la resina en una o más fibras; enfriar la una o más fibras por debajo del punto de solidificación de la resina; después de enfriar, estirar la uno o más fibras hasta un alargamiento nominal de 50 a 900% para formar una o más fibras estiradas; y relajar la una o más fibras estiradas para formar una o más fibras elásticas, y, opcionalmente, laminar las fibras a un sustrato flexible. Los artículos que comprenden tales fibras elásticas unidas a un material no tejido pueden exhibir: una fuerza al 50% de alargamiento menor de 2 Newtons, una fuerza al 100% de alargamiento menor de 4 Newtons, un alargamiento a cinco Newtons para una muestra de 5 mm. de al menos 120%, y/o una fuerza de descarga al 50% en un segundo ciclo menor de 1,5 N/50 mm.
